Examples

Referring to fig. 2, fig. 3, fig. 4, fig. 6 and fig. 12, in an embodiment of the wheeled tractor drill, the wheeled tractor drill includes a derrick tractor 1, a tractor base 2, a hydraulic station 6, a winch 5 and a derrick 3; the derrick towing attachment 1 comprises a derrick trailer 19; the towing base device 2 comprises a base upper seat 21 and a towing base 22, the base upper seat 21 is connected with a derrick base and the attached equipment of the derrick base, a derrick trailer 19 is in pin connection with the towing base 22 through a pin shaft, and the base upper seat 21 is provided with a derrick connecting part; the derrick 3 is connected with the derrick towing device 1, a towing base connecting part is arranged on the derrick 3, and the towing base connecting part is connected with the derrick connecting part when the drilling machine works; the hydraulic station 6 and the winch 5 are each arranged on a derrick trailer 19 in the derrick towing installation 1.

The wheel type traction drilling machine further comprises a crown block 7 arranged at the top of the derrick 3 and a traveling block 8 matched with the crown block 7, wherein the traveling block 8 is connected with a top drive, a slurry pump and a turntable which are arranged at the bottom of the derrick 3.

The hydraulic station 6 in the present embodiment may be a part of a wheeled tractor-drill or may be an external hydraulic system that is temporarily built.

Specifically, the derrick trailer 19 is provided with the first connecting ear plate 15, the hanging base 22 is provided with the second connecting ear plate 262, and when the first connecting ear plate 15 and the second connecting ear plate 262 are aligned to make the hole sites of the two coaxial, the pin shaft is simultaneously inserted into the first connecting ear plate 15 and the second connecting ear plate 262 to form a pin connection.

It can be understood that, in this embodiment, before the transportation, the pin shaft is taken down from the first connecting ear plate 15 and the second connecting ear plate 262, so as to separate the derrick towing device 1 and the towing base device 2, and since the derrick towing device 1 and the towing base device 2 are respectively provided with the derrick trailer 19 and the towing base 22, the derrick towing device 1 and the towing base device 2 can be transported integrally by the tractor 4, so as to avoid the disassembly of the base device; after moving, the base device 2 is parked at the preset position of the wellhead, and after the first connecting lug plate 15 on the derrick dragging device 1 is aligned with the second connecting lug plate 262 on the base device 2, the drilling machine can be assembled by penetrating the pin shaft, so that the base device is prevented from being assembled independently.

In the assembly process of the derrick towing device 1 and the towing base device 2, the alignment of the first connecting ear plate 15 and the second connecting ear plate 262 is generally realized by reversing the towing vehicle 4; however, in each reversing operation, a worker cannot control the displacement generated by the derrick towing device 1 well, and often needs to reverse several times to align the first connecting lug plate 15 and the second connecting lug plate 262, which is time-consuming and reduces the overall efficiency of the movement of the drilling machine, so in an embodiment, referring to fig. 6 and 7, the derrick towing device 1 further includes a sliding body 14, a longitudinal moving mechanism 13, a first jacking mechanism 12 and a second jacking mechanism 11; the plane outline of the derrick trailer 19 is generally rectangular, and one end of the derrick trailer 19 is provided with a first connecting lug plate 15; the derrick trailer 19 is connected with the sliding body 14 in a sliding way, and the slidable direction of the sliding body 14 is along the long axis direction of the derrick trailer 19; the longitudinal moving mechanism 13 has two ends capable of moving in opposite directions, wherein one end is connected with the sliding body 14, the other end is connected with the derrick trailer 19, and the sliding body 14 slides relative to the derrick trailer 19 under the driving of the longitudinal moving mechanism 13; one end of the first jacking mechanism 12 is connected with the sliding body 14, and the other end is used as a free end to selectively contact with the ground, so that the derrick trailer 19 is jacked; the second jack-up 11 is connected to the derrick trailer 19 at one end and is in selective contact with the ground as a free end at the other end, thereby enabling jack-up of the derrick trailer 19.

Specifically, the longitudinal moving mechanism 13, the first jacking mechanism 12 and the second jacking mechanism 11 are respectively configured as oil cylinders so as to be suitable for heavy-load occasions and ensure the safety of construction; the number of the first jacking mechanisms 12 is four, two of the first jacking mechanisms 12 are arranged on one axial long side of the derrick trailer 19, the other two first jacking mechanisms 12 are arranged on the other axial long side of the derrick trailer 19, the fixed ends of the first jacking mechanisms 12 are fixedly connected with the sliding body 14, and the moving ends of the first jacking mechanisms 12 are used as free ends and can be in contact with the ground when the moving ends act; the number of the second jacking mechanisms 11 is four, two of the second jacking mechanisms 11 are fixedly connected to one side of the derrick trailer 19 in the long axial direction through fixed ends of the second jacking mechanisms, the other two second jacking mechanisms 11 are fixedly connected to the other side of the derrick trailer 19 in the long axial direction through fixed ends of the second jacking mechanisms, and moving ends of the two second jacking mechanisms 11 on the two opposite sides are connected through a supporting plate, so that the derrick trailer 19 is prevented from sinking below the ground in the supporting process. a. The first jacking mechanism 12 is used as a support of a derrick trailer 19, the second jacking mechanism 11 is retracted, and at the moment, the derrick trailer 19 is driven to slide relative to the sliding body 14 by driving the longitudinal moving mechanism 13, so that the integral translation of the derrick trailer 19 can be realized; after the completion of the translation, b. using the second jacking mechanism 11 as a support for the derrick trailer 19, the first jacking mechanism 12 is retracted, and at this time, the sliding body 14 and the first jacking mechanism 12 are slid relative to the derrick trailer 19 by driving the longitudinal moving mechanism 13, and at this time, the sliding body 14 is returned to the initial position. Repeating a, b allows for a continuous displacement of the derrick trailer 19.

It will be appreciated that the distance of movement of the derrick trailer 19 per time can be determined by the stroke of the longitudinal movement mechanism 13 and the sliding stroke of the sliding body 14.

It will be appreciated that the distance of movement of the derrick trailer 19 per pass can be accurately controlled by the size of the stroke of the longitudinal movement mechanism 13.

In an embodiment, referring to fig. 7 again, in order to ensure the simultaneity of sliding on both sides of the long axis of the derrick trailer 19 and make the sliding body 14 have enough supporting strength, the sliding body 14 is constructed into a beam structure, two sliding bodies 14 are arranged in the derrick trailer 19 along the short axis direction of the derrick trailer 19 and the sliding body 14 forms relative sliding with the derrick trailer 19 in the long axis direction of the derrick trailer 19, the two sliding bodies 14 are respectively arranged at both ends of the derrick trailer 19 in the long axis direction, and both ends of the sliding body 14 are respectively connected with the first jacking mechanism 12.

When the longitudinal moving mechanism 13 on one side of the long axis of the derrick trailer 19 is driven, the longitudinal moving mechanism 13 on the other side can be driven by the sliding body 14, so that the action simultaneity of the longitudinal moving mechanisms 13 on the two sides is ensured to a certain extent; at the same time, the provision of the beam structure can provide a structural foundation for the derrick trailer 19 to have a large contact area with the skid 14, so as to prevent stress concentration.

When the derrick trailer 19 is stopped at the initial adjustment position by the tractor 4, the angle of the derrick trailer 19 is not necessarily a desired angle, and it is mentioned above that the adjustment of the angle by the tractor 4 requires a high operation requirement, which is time-consuming and labor-consuming, and in order to facilitate the alignment of the derrick trailer 19 with the wellhead, in one embodiment, the derrick trailer comprises a traversing mechanism 16, the traversing mechanism 16 has two ends capable of moving in opposite directions, one end of the two traversing mechanisms 16 is hinged to the two sliding bodies 14, and the other end of the two traversing mechanisms 16 is hinged to the derrick trailer 19; the opposite directions of movement in the two traversing mechanisms 16 are parallel; the longitudinal moving mechanism 13 is respectively hinged with the sliding body 14 and the derrick trailer 19; in the working state, the hinge connection structure has a rotational degree of freedom in a horizontal plane.

In particular, the traversing mechanism 16 is also configured as a cylinder, the moving end of the traversing mechanism 16 is articulated with the sliding body 14, and the fixed end of the traversing mechanism 16 is articulated with the derrick trailer 19.

It can be understood that depending on the installation posture of the traversing mechanism 16, the extension and retraction of the two traversing mechanisms 16 are different, as follows: when the two traversing mechanisms 16 are located on the same side (e.g., left or right) of their respective attachment points with respect to the attachment points of the traversing mechanism 16 to the derrick trailer 19, the two traversing mechanisms 16 move in opposite directions upon rotation of the derrick trailer 19, e.g., one traversing mechanism 16 extends and the other traversing mechanism 16 retracts; when the two traversing mechanisms 16 are located on different sides of their respective attachment point (e.g. one left side and the other right side), the two traversing mechanisms 16 themselves move in the same direction towards each other, e.g. both traversing mechanisms 16 extend or retract simultaneously, when the mast trailer 19 is rotated.

It should be noted that depending on the installation position of the traversing mechanism 16 itself, it is not necessary that the traversing mechanism 16 rotate in the horizontal plane when the derrick trailer 19 is carried by the longitudinal moving mechanism 13. For example, when the axis of traversing mechanism 16 is parallel to the long axis of mast trailer 19, and when the longitudinal moving mechanism 13 is driven to move mast trailer 19, the traversing mechanism 16 does not rotate in the horizontal plane, as viewed from the normal to the bottom of mast trailer 19; when the axis of the traversing mechanism 16 is not parallel to the long axis of the derrick trailer 19, and the longitudinal moving mechanism 13 is driven to move the derrick trailer 19, the traversing mechanism 16 rotates in the horizontal plane.

As mentioned above, the rotation center of mast trailer 19 differs according to the relative position of the connection points of the two traversing mechanisms 16 and mast trailer 19; if the two aforementioned connection points are located on the same side of the long axis of mast trailer 19 and the centre of rotation of mast trailer 19 is located on one side of the long axis of mast trailer 19, then the space required for physically rotating mast trailer 19 on the other side of the long axis is greater during rotation; for example, two sliding bodies 14 and the edges of two sides of derrick trailer 19 are enclosed into a rectangular area, if the rotation center is not located on the centroid of the rectangular area, the rotation radius of two opposite corner points on two sides is different, in order to balance the rotation space on two sides of the long axis of derrick trailer 19 as much as possible, in one embodiment, the connecting line center of the connecting points of two traversing mechanisms 16 and derrick trailer 19 is located on the long axis of derrick trailer 19 in the normal view along the bottom of derrick trailer 19, that is, the two connecting points are located on two sides of the long axis of derrick trailer 19, and the distance between the two connecting points and the long axis of derrick trailer 19 is equal in the normal view along the bottom of derrick trailer 19.

It will be appreciated that the midpoint of the line connecting the two points of attachment is the center of rotation of mast trailer 19.

According to the above, when the traversing mechanisms 16 are hinged to the sliding body 14 and the derrick trailer 19, respectively, as long as the opposite moving directions of the two traversing mechanisms 16 are not coincident, the derrick trailer 19 can rotate under the driving of the two traversing mechanisms 16, but in order to enable the traversing mechanisms 16 to drive the derrick trailer 19 to move in a direction parallel to the short axis of the derrick trailer 19, in a preferred embodiment, the traversing mechanisms 16 have an axis parallel to the short axis of the derrick trailer 19 in the installation posture, and the connecting point of the traversing mechanisms 16 and the derrick trailer 19 is located at the midpoint of the short axis in the view of the long axis of the derrick trailer 19, and the derrick trailer 19 can move in a direction parallel to the short axis of the derrick trailer 19 when the traversing mechanisms 16 are driven in the same direction or in the opposite direction.

It will be appreciated that the arrangement of the traversing mechanism 16 and the longitudinally moving mechanism 13 enables movement of the mast trailer 19 in two mutually orthogonal directions, thereby enabling displacement of the mast trailer 19 at any position in a plane, which in turn reduces the initial parking position requirements of the tractor 4.

The long axis and the short axis mentioned above mean: the projection profile of the derrick trailer 19 in the normal direction of the bottom thereof is generally rectangular, the connecting line of the midpoints of the two long sides is a short axis, and the connecting line of the midpoints of the two short sides is a long axis; of course, the projected outline may not be a strict rectangle, since the two short sides of the projected outline may be curved or broken lines, and in this case, a standard rectangle is constructed on the basis of the long side to define the long axis and the short axis.

When the longitudinal movement mechanism 13 causes the sliding body 14 to slide relative to the derrick trailer 19, the traverse mechanism 16 is configured to follow relative to the sliding body 14, i.e., the sliding body 14 causes the moving end of the traverse mechanism 16 to move.

It will be understood that the opposite direction of movement here is the direction of movement of the traversing mechanism 16 in the mounted state.

In the related art, as shown in fig. 1, the derrick 1 ' is more of a rope-break-free structure, the overall weight of the derrick 1 ' is greatly increased, the structural strength requirement on the derrick towing device 2 ' is higher, and the load requirement on the towing vehicle is also higher and stricter, and a load-sharing towing vehicle is generally adopted to share the load of the towing vehicle, but because the weight is greatly increased, the operation requirement for directly driving the derrick towing device 2 ' to adjust the position by the towing vehicle is higher, and if the load-sharing towing vehicle is added, the operation requirement is further increased, so that the aligning efficiency of the derrick towing device 2 ' and the wellhead is lower. In order to solve this problem, in an embodiment, referring to fig. 2, a first connection portion for installing the winch 5 is provided on the top of the derrick trailer 19, the first connection portion is located on one side of the saddle of the derrick trailer 19 and on one end of the derrick trailer 19 in the long axis direction, and the derrick trailer 19 is provided with a second connection portion for connecting to a position on the tractor 4 close to the head through an axle.

The winch 5 is located at one end of the long axis direction of the derrick trailer 19 through the arrangement of the first connecting portion, and the load of a saddle position can be balanced through the cantilever load of the winch 5, so that the pressure of an axle to the tractor 4 can be reduced, and then the condition of canceling the partial load trailer is met.
